This 9-pin D-sub connector is used to connect the AD824 to the next AD824 in a mul-
tiple-unit system.

COM PC/RS422 switch
This switch should be set to RS422 when the COM PC/RS422 port is connected to a
DME32 or the previous AD824 in a multiple-unit system, or PC when it’s connected to
a PC.
Security Cover
For certain applications you may wish to fit a protective cover over the AD824’s GAIN
controls and switches. Although Yamaha do not make such a cover, the AD824 has four
fixing holes to affix a custom-made cover. If you fit such a cover, make sure that the fixing
screws do not protrude inside the AD824 by more than 10 mm. The fixing holes accept
M3-size machine screws, and are spaced 45.0 mm vertically, 410 mm horizontally.
